Summary

This small pilot study tested whether a gentle electrical current applied to the brain (tACS) could improve naming ability in 11 people with chronic aphasia after a stroke. Participants received either real or sham stimulation during language training over two weeks. The goal was to see if the real stimulation led to better naming of pictures they previously couldn't name.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: transcranial alternating current stimulation (tACS)
What this could lead to: If it works, this could point toward a non-invasive way to boost language recovery after stroke.
What could go wrong: This is a very small pilot study (11 people) with no phase, so results may not apply widely. The effect may be small or due to placebo.
